Found only in the western portion of the state, primarily in the Taconic Mountains and Vermont Valley. With the exception of the one northerly record, the distribution looks very similar to that of Arigomphus villosipes. Within its range, it has been found primarily along rivers, but also has a couple of records from lake/pond situations. First recorded in Vermont in 2003, with approximately six sites with adult records to date. Has a relatively short recorded flight season.
